FAQs - Peterbilt 379 Steer Axle Spring Hangers

1. What do steer axle spring hangers do? They connect the front leaf springs to your truck's frame and help hold your steer axle in place. Basically, they're key to your suspension staying stable and aligned. 2. How do I know if my spring hangers are bad? Look for cracked hangers, worn bushings, or misaligned front suspension. If your steering feels loose or uneven, it's time to check your hangers. 3. Are these hangers a direct fit for the Peterbilt 379? Yep. These are made to match OEM specs for the 379. Just double-check your year and suspension setup before ordering. 4. Do I need new hardware or bushings with a hanger replacement? It's a good idea. If your hanger's worn out, the bolts, pins, or bushings likely are too. Grab a full kit if possible for a proper fix. 5. Can I install spring hangers myself? If you ve got suspension experience and the right tools, yes. But it's a heavy-duty job that might need frame support and a press, so many guys take it to a shop. 6. Are these hangers sold individually or in pairs? Most are sold individually, but we also offer kit options. Always check the listing to be sure. 7. Do these work with aftermarket leaf springs? They can, as long as the spring dimensions match OEM. Always double-check the hanger's bolt pattern and spring eye size. 8. What suspension types are these compatible with? Most work with standard leaf spring setups on the 379, but not all will fit custom suspensions or lowered trucks. Match it to your setup before you buy.
